MULTIPLE-WlNDOW-OPERATING NIEOHANISM'l Speccaton of Letters Patent.

Patented Jan. 29, 1907.

Application filed October 10, 1906. Serial No. 338,273.

To @ZZ whom, t may concern:

Be it known that I, ADOLPH G. PITZ, a citizen of the United States, residing at Bridgeport, county'of Faireld State of Connecticut, have invented a new and useful Multiple- Vindow-Operating Mechanism, of which the following is a specification.

This invention has for its object to provide simple, durable, inexpensive, and easily-operated mechanism for operating simultane- -ously a plurality of windows which may be placed in a circular or polygonal cupola or dome or upon the four sides of a monitorroof, said windows being easily connected to and disconnected from the operating mechanism, so that they will remain in any position in which they may be placed, either closed or wholly or partly open when the connected windows are opened or closed by the operating mechanism.

In the accompanying drawings I have illustratedmy novel operating mechanism as applied to the windows of a monitor-roof. I wish it distinctly understood, however, that it is wholly immaterial so far as the principle of the invention is concerned whether the windows in a group to be operated are arranged in a plurality of sides or in the form of a circle.

Figure 1 is a horizontal section of a monitor-roof on the line 1 1 in Fig. 2; Fig. 2, a vertical section on the line 2 2 in Fig. 1 looking in the direction of the arrows; Fig. 3, a detail front elevation of the operating mechanism, on an enlarged scale, the operatingwheel bein(r removed and the shafts in section on therline 3 3 in Fig. 4; Fig. 4, a side elevation of the operating mechanism; Fi 5, a detail elevation of one of the cable-gui i es removed; Fig. 6, an elevation of one of the operating-arms and cable-clamps detached, and Fig. 7 is a plan view corresponding therewith.

10 denotes framework, asfthe frame of a monitor-roof, and 11 windows, shown as pivoted to said framework so as to swing in the vertical plane, the pivotal points of the windows being indicated by 12. For the sake of clearness in illustration I have shown two windows only in the sides of the monitorroof and one window at each end. It should be understood, however, that mynovel mechanism willoperate a large number of windows simultaneously, as in the monitor-roofs of large foundries, cc.

13 denotes upper and 1,4 lower cable-guides carried by brackets 15, which are rigidly secured to the framework. In the present instance I have shown cable-guides consisting of grooved pulleys 16, arranged in pairs, which just receive the cable 17 between them. This cable is continuous and passes twice around the framework, the upper part of the cable being attached to each window by an operating-arm 18, connected to one side of the frame and the lower part of the cable being connected to the opposite side of each window-frame by an operating-arm 19. The connection of the arms to the windows is made by means of universal joints 20, carried by brackets 21, which are rigidly secured to the window-frames. The opposite end of each operating-arm is connected, by means of a universa joint 22, to a cableclamp 23, each clamp consisting of two members provided with grooves 24 to receive the cable. The members of the clamp are rigidly locked to the cable by means of bolts 25 passing through the members and provided with nuts 26. The cable passes twice about a drum 27, carried by a shaft`28, journaled in a bracket 29, which is ri idly securedv to the framework. Shaft 28 a so carries a gear-wheel 30, which is driven by means of a pinion 31 on a shaft 32, also journaled in bracket 29 and carrying an operating-wheel 33. A chain 34, passing over the operatingwheel, provides means for operating the entire series of windows simultaneously fromv the iioor below.

The course of the cable is as follows: Starting from the drum in Fig. 1, what I have termed the Hupper part of the cable eX- tends toward the right, passes around the framework and through the upper guides 13, is connected to one side of each window-frame, passes back to the drum, then down about the drum and toward the left, comprising what I have termed the lower part of the cable, passes entirely around the framework again, through the lower guides 14, is connected to the opposite sidev of each windowframe, passes back to the drum and upward over the drum to the starting-point. It will be noted that the upper and lower parts of the cable both extend in opposite directions from the drum. In use suppose the operating-wheel to be turned toward the right as seen in Figs. 1 and 2. The upper part of the cable will be moved toward the right and the lower part toward the left, the effect of which will be to swing the bottoms of the windows outward from the point of view toward the IOO ILO

open position. To close all of the windows simultaneously the operating-wheel is turned toward the left, which will move the upper art of the cable toward the left and the ljower part toward the right as seen in Figs. l and 2, thereby swinging the bottoms of the windows inward to place and fully closing them. Should it be required to leave any of the windows in either the closed or a partly or wholly open positionI the windows are locked in any suitable manner in the desired position and the cable-clamps of the windows not to be operated are loosened so that the upper and lower parts of the cable will slide freely through the clamps.

Having thus described my invention, I claiml. An operating mechanism for a plurality of vertically-swinging windows, consisting of a cable comprising upper and lower partsJ means for connecting said parts respectively to opposite sides of each window and means for moving the parts of the cable in opposite directions whereby the windows may be opened or closed.

2. An operating mechanism for a plurality of' swinging windows, consisting of a cable comprising upper and lower parts, means for connecting said parts respectively to the opposite sides of the window-frames, upper and lower guides consisting cf pairs of grooved rollers through which the parts of the cable pass and means for moving the parts of the cable in opposite directions.

3. An Operating mechanism for a plurality of swinging windows, consisting of a cable comprising upper and lower parts, means for connecting said parts respectively to the opposite sides of the window-frames, a drum about which the cable passes twice, the upper and lower parts of the cable extending in opposite directions from the drum and means for rotating the drum to open or close the windows.

4. An operating mechanism for a pliuality of swinging windowsI consisting of a cable comprising upper and lower parts, means for connecting said parts respectively to the opposite sides of the window-frames, a drum about which the cable passes twice, the upper and lower parts of the cable extending in opposite directions from the drum, a gearwheel moving with the drum, a pinion engaging said gear-wheel and an operating wheel and chain by which the pinion is rotated to open or close the window.

5. An operating mechanism for a plurality of swinging windows, consisting of a cable comprising upper and lower parts, detachable connections between the parts of the cable and the opposite sides of the windowframes and means for moving the parts of the cable in opposite directions.

6. An operating mechanism for a plurality of swinging windows, consisting of a cable comprising upper and lower parts, operatingarmsI universal joints connecting said arms with the opposite sides of the windowframes, clamps detachably engaging the parts of the cable7 universal oints connecting the opposite ends of the operating-arms with the clamps and means for moving the parts of the cable in opposite directions.

In testimony whereof I aHiX my signature in presence of two witnesses.

ADOLPH G. PITZ.
